Transaction Submission (API v2)
Nozomi sends transactions through multiple channels to achieve best performance.
sendTransaction2
The /api/sendTransaction2 endpoint is not compatible with the Solana JSON-RPC sendTransaction method. Requests sent via the /api/sendTransaction2 endpoint from browser clients will see better performance, as this endpoint will skip the OPTIONS preflight request triggered by normal Solana JSON-RPC methods.
The /api/sendTransaction2 endpoint does not return a transaction signature on success. A successful request will return an empty body with a 200 OK status code.
Benefits
Eliminates CORS Preflight: Skips OPTIONS preflight requests that add 50-100ms latency
Faster Encoding: Base64 encoding/decoding is significantly faster than base58 operations
Reduced Body Size: Base64 encoding is more compact than base58 serialization used in JSON-RPC
Lower Bandwidth Usage: Smaller payloads reduce network transfer time and costs
Lower Network Overhead: Plain text payload avoids JSON parsing overhead
How to Use
Content-Type: text/plain
HTTP Method: POST
Body Format: "<YOUR_BASE_64_ENCODED_TXN_BYTES>"
Just add API Key after ?c=<uuid> to get custom URL for sending.
